How to use HTML5 Geolocation Latitude/Longitude API?

HTMLWeb DevelopmentFront End Technology

HTML5 Geolocation API lets you share your location with your favorite websites. A JavaScript can capture your latitude and longitude and can be sent to backend web server and do fancy location-aware things like finding local businesses or showing your location on a map.

The geolocation APIs work with a new property of the global navigator object ie. Geolocation object.

Example

You can try to run the following code to find the current location using the Geolocation API, with Latitude and Longitude coordinates

            var longitude = position.coords.longitude;
            alert("Latitude : " + latitude + " Longitude: " + longitude);
         }
         function errorHandler(err) {
            if(err.code == 1) {
               alert("Error: Access is denied!");
            } else if( err.code == 2) {
               alert("Error: Position is unavailable!");
            }
         }
         function getLocation(){
            if(navigator.geolocation){
               // timeout at 60000 milliseconds (60 seconds)
               var options = {timeout:60000};
               navigator.geolocation.getCurrentPosition
               (showLocation, errorHandler, options);
            } else{
               alert("Sorry, browser does not support geolocation!");
            }
         }
      </script>
   </head>
   <body>
